Description

INFOID:0000000007578252

Suppresses the deployment of front passenger air bag when the condition of passenger seat is empty or occu-
pied with a child and child-seat. Also illuminates front passenger air bag OFF indicator lamp when the condi-
tion of passenger seat is occupied with a child-seat and child. In case of malfunction the blinking of the air bag
warning lamp reports the malfunction to driver, and by the on board self-diagnosis system or CONSULT can
detect the cause.

OPERATION

This unit classifies occupant in passenger seat and detects electrical malfunction in Occupant Detection Sys-
tem and transmits malfunction information to air bag control unit.

STRUCTURE

It is integrated into the seat sensor mat and detects the occupants and Occupant Detection System control
unit that classifies the occupants.

INSTALLATION

Occupant Detection System control unit is installed in the passenger seat cushion.
